日本光明理化学工业株式会社在气体分析领域开拓了六十年,形成了于世的“北川”式气体快速分析法,“北川”的历史就是检测管的历史。
检测管的特长:无论何时:由于不用分析仪器和化学药剂,省略了测量前的准备工作,无论何时都可以进行测定
- 无论何地:极为小巧便于携带,只要有微量的空气就可以进行测定,适合于现场测定
- 无论何人:测定的操作非常简单,无论人士或非人士
- 多种气体:可以检测多达400余种气体
- 快速:测定的结果几分钟就可得到,可以立即转入下一步操作
- 安全:不用电源、热源,即使有易燃易爆的气体存在也可以确保操作安全
检测管的用途:作业环境的测定:日本劳动省颁布的《作业环境操作标准》中采用了本公司的13种测试管,用途以现场作业为主,另外在建筑、事务所等环境保护工作中也有着广泛的应用
- 防火、防爆:可以在现场快速的测定可燃性气体的浓度,广泛用于检测易燃易爆气体的泄漏、生产,以防止火灾、爆炸事故的发生
